About Domain IDs
The configured domain ID can be preferred or static. By default, the configured domain ID is 0 (zero)
and the configured type is preferred.
Note
The 0 (zero) value can be configured only if you use the preferred option.
If you do not configure a domain ID, the local switch sends a random ID in its request. We recommend
that you use static domain IDs.
When a subordinate switch requests a domain, the following process takes place (see Figure 33-2 ):
1.
The local switch sends a configured domain ID request to the principal switch.
2. The principal switch assigns the requested domain ID if available. Otherwise, it assigns another
available domain ID.
